WINDOW AFRAME AND SASH.

SPECIFICATION forming part of Letters Patent No. 576,486, dated February 2, 189'?. Application filed April 25, 1896. Serial No, 589,061. (No model.)

To @ZZ whom, 'zit may con/cern.Y

Be it known that I, DAVID W. TROTTER, of Butte, in the county of Silver Bow and State of Montana, have invented a new and useful Improvement in Vindow Frames and Sashes, of which the following is a full, clear, and eX- act description.

vMy invention relates to the construction of window-frames and window-sashes; and the object of the invention is to provide a means whereby the defects of windows as at present hung will be almost eliminated and the windows will be rendered almost entirely dust and wind proof, friction being reduced to a minimum.

A further object of the invention is to so construct the window sashes and Iframes that the necessity of :inside stops and parting- `beads will be dispensed with, and whereby the sashes may be more readily removed from the window-fra1ne than under the present system.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the gures.

Figure l is a front elevation of a windowframe and the sashes therefor. Fig. 2 is a vertical section through the window frame and sashes, both sashes being closed. Fig 3 is a horizontal section taken practically on the line. 8 3 of Fig. l. Fig. 4: is a front elevation of the upper and lower window-sashes removed from the window-frame- Fig. 5 is an edge view of the aforesaid upper and lower sashes. Fig. 6 is a vertical section through the sashes, taken practically on the line 6 6 of Fig. 4. Fig. 7 is a horizontal section through the upper sash, taken on the line 7 7 of Fig. 4, the lower sash being in plan View. Fig. 8 is a detail perspective view of the upper portion of one of the yoke-guides of the window-sash. Fig. 9 is a side elevation of the upper portion of one end of the said guides, illustrating the application of the sash-cords thereto; and Fig. l0 is an edge view of the upper portion of the guide for the sash, the sash-cord being likewise connected therewith.

' In carrying out the invention both the upper sash A of the window and the lower sash B are provided in their side edges with grooves lO and with grooves 1Gn in Itheir lower edges, the upper sash A being also provided with a groove ll in its top rail. The side and bottom grooves of the window-sashes are adapted to receive yokes C, which vokcs are preferably made of metal, and each yoke consists of a vertical member'and'a horizontal foot member, and the vertical members of the yokes are fitted in the aforesaid grooves l0 and I6, extending a predetermined distance i outward beyond the side edges of the sash, while the upper ends of thesaid yokes extend above the upper rails of the sashes, and are provided at that point preferably with an L or a T shaped groove l2, the groove being made in the inner edge of the aforesaid yoke members, and the sash-cords 13 are attached, preferably, directly to the upper ends of the guide-yokes C, as shown in bigs. 9 and l0.

Each sash-cord is ordinarily provided with a ferrule 14, terminating in an eye 15, the eyes being introduced into the slots or grooves l2 of the guide-yokes. The foot members of the yol'res enter the respective bottom grooves 16" in the sashes.

A rib 16 is made in the upper face of the sill 17 of the window-frame D, as shown particularly in Fig. 2, and the said rib is of such length that it will iill the groove loL in the lower sash between the foot portions of its yokes when the said lower sash is lowered. Un der this construction the wind and dust are prevented from entering the room between the sill and the lower sash. Each sash-cord 13 is preferably carried upward and over a pulley 16h, the lpulleys being located ordinarily in a compartment 17, provided for them in the upper portions of the window-frame, as illustrated in Figs. l and 2, and each sashcord has attached to it a weight 18 or the equivalent of the same. The pulleys 16b are preferably housed, or they may be simply journaled in proper supports located in the aforesaid upper compartments of the frame.

The lower sash is nearly balanced, and the top sash is preferably lighter than its at- ISO tached weights, so that the sashes will close quickly and easily. At the top portion of the Window-frame a strip 19 is introduced and secured, preferably made of metal, and this strip when the upper sash is closed will enter the upper groove 11 in the said upper sash, as shown in Fig. 2,'and prevent the ingress of Wind or of dust at the upper portion of the window-frame.

The ordinary sash-grooves may be dispensed with in this form of the Window frame, and instead a longitudinal vertical groove 2O is made in the vertical jambs 2l of the aforesaid frame, as illustrated in Fig. 3, and the said grooves 20 in the sides of the window-frame are adapted to receive theprojecting side portions of the guide-yokes C of the windoW-sashes.

In order to detach the guide-yoke from the lower sash, I detach the sash-cords, push the sash to the top of the frame, and then draw the yoke out. The yoke beingmade of metal will spring enough to admit of such action, especiallyas the yoke is longer than the sash. In taking the yoke from the top sash I draw the sash down, disconnect the sash-cords, push the sash back to place, and draw out the yoke. The aforesaid side members of the sash guide-yokes are held in their outward position when in the sashes or outwardly to such an extent that they will fully enter the guide slots or grooves 2O in the Windowfrarnes by means of springs 22, (shown in Fig. 4,) which are located Within recesses made in the side edges of the sashes at the inner walls of their vertical grooves I0.

It is obvious that under the foregoing construction of sashes any window-frame may be readily adapted for their reception, and

that when the frame is particularly manufactured to receive the sashes it will be less expensive than the ordinary form of frame.

In order that the sash guide-yokes and the sashes shall positively move together, a button or plate 23 is secured to the top of the sash at one or both sides, and the said buttons enter recesses 24 in the inner edges of the upwardly-extendingportions ofthe yokes, as shown in Figs. 5, 6, and 8.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A Window-sash provided With grooves extending through its side and bottom edges, two L-shaped yokes, the longer portions of which are itted in the vert-ical slots at the side edges of the sash and the shorter p0rtions of which are pivoted in the horizontal slot at the bottom edge of the sash, and a plate for each yoke, the plates being respectively tted in slots formed in the upper extremities of the yokes and the plates lying snugly against the upper edge of the sash to prevent the accidental downward movement of the yokes, substantially as described.

2. A window-sash having grooved side and bottom edges, L-shaped yokes having their vertical portions fitted within the grooves in the side edges of the sash and their horizontal portions fitted Within the groove in the bottom edge of the sash, the upper extremities of the yokes being respectively extended above the sash and each of said upper extremities being provided with a slot forming a hook, the hook being adapted to carry a Weight-cord, and each yoke also having a recess respectively adjacent to the slots and a plate for each recess of the yokes, the plates respectively fitting Within the recesses and bearing against the upper edge of the sash, substantially as described.

DAVID W. TROTTER.
